Hey 

 

The bane of my life is this bloody glass floored external balcony .

A key issue is the 2 structural steels that support the glass .

Most companies want to powder coat etc with a mega price attached !

Anyone tried any steel paint ?

Im tempted to buy some and simply paint some of the internal structural steel just to test how it looks .

I assume someone else has done this and has some exposed painted steel they can show me .....

In the past i have used liquid galvanised  paint as a base coat and then a two part paint to finish, seemed bomb proof. Can you not just get the components hot dipped galvanised ? Did this a lot when i was in Australia, you cant paint it for some time after dipping though......

If it were me, if any of its outside the interior envelope, id prime it with this :http://www.rust.co.uk/custom-421-rust-proofing-body-primer/c32736/

 

When i did my steels, I painted them with automotive direct gloss 2 pack. Sprayed. But over etch primer as it was all inside.

 

But you could do it with a roller, which will be close in terms of finish, but will require 3-4 coats as its quite runny. The end result will be tough, resist rust, and if you spray it look really good.

 

Dont spray 2 pack without the right gear though!

How big are they ..? I’ve had stuff powder coated and it’s not that expensive. And I agree with @Cpd that galvanising is as good - or better - and not that pricey as they do it by weight.

What he means is don’t spray 2 pack unless you have a full set of air fed masks and full extraction as it has the ability to kill you .... 

 

Just for the avoidance of doubt and all that... 9_9

About 7meters long shaped like a box 

They wanted 6k for two like that claiming the powder coating was the cost . The structural steel I know isn’t that expensive really .....

Quick question. Do they need to be fire rated at all? If so you will need an intumescent paint in it somewhere. 

Nope :-)

If they're just straight sections then some are available galvanized off-the-shelf...

You would need a big oven for power coating something that size. When I've had 6m long aluminium angle power coated in the past they've had to put it in diagonally.

Get them galvanized. I've had powder coated steel rust on a project. Admittedly it's on the edge of Ireland facing the Atlantic but it is rusting where galvanized beside it isn't. I haven't specified powder coated structural steel since anywhere.

I used to have a lot of stuff fabricated. You can powder coat over galvanised steel. As a pretty good but lesser option powder coat over zinc flame sprayed steel after first shot blasting to Swedish Standard SA2.5. To powder coat straight onto bare steel is madness imho. A lot of lads do it on their car suspension components, subframes etc. One crack or chip and water gets in and under the powder coat.

Like others have said, just galvanise - don't bother with the powder coat.

I used to design steel balconies and never, ever, powder coated structural steels. One coat primer, one undercoat and one top coat, or a combination of specialist paints should be fine. Powder coating tends to chip and also loses its gloss. As it's plastic it might fade in the sun too.
